Deck board



FIG. 1 is a perspective view of a deck board, showing my new design;

FIG. 2 is a front elevational view thereof, the rear elevational view being a mirror image thereof;

FIG. 3 is an end elevational view thereof;

FIG. 4 is a top plan view thereof; and,

The broken lines in FIGS. 1, 2, 4 and 5 depict the deck board having indeterminate length. 

I claim the ornamental design for a deck board, as shown and described.
